Predictors of Semen Parameters Decline Following the Microsurgical Varicocelectomy.

Objective Varicocele is considered the most common reversible cause of male infertility. However, some men do not clinically improve after surgical repair. We aimed to identify preoperative factors associated with decreased semen parameters and clinical "downgrading" of total motile sperm count (TMSC) following varicocelectomy.

Assessing the Prevalence of Low Testosterone and Elevated Follicle Stimulating Hormone Among Men Presenting for Fertility Evaluation Without Oligospermia.

Objective: To compare the prevalence of abnormal hormone parameters among men with and without oligospermia to determine the value of universal hormonal screening during initial fertility evaluation.

Materials And Methods: We retrospectively evaluated men who underwent semen analysis and hormonal evaluation (morning testosterone [T] and follicle-stimulating hormone [FSH]) between January 2002 and May 2021. Sperm concentration was dichotomized at 15 million/mL according to World Health Organization (WHO) criteria.

Self-Reported Race/Ethnicity Is Not Associated with Abnormal Semen Parameters after Accounting for Body Mass Index and Socioeconomic Status.

Purpose: We evaluated whether consideration of body mass index (BMI) and socioeconomic status alters the reported association between race/ethnicity and abnormal semen parameters.

Materials And Methods: We conducted a retrospective review of all men who underwent semen analysis (SA) for fertility evaluation at an integrated academic health care system from 2002 to 2021. Men were excluded if they had a diagnosis of Klinefelter's syndrome, history of varicocele, prior testicular surgery, prior history of chemotherapy or radiation for cancer, or prior testosterone-modulating medication use.

A qualitative assessment of return to sport following Achilles tendon repair.

Studies have demonstrated successful return to sport rates following Achilles tendon rupture and repair. The purpose of this study is to understand the subjective intrinsic and extrinsic motivational factors influencing an athlete's return to pre-injury level of sport following Achilles tendon repair. Qualitative, semi-structured interviews of 23 athletes who had undergone Achilles tendon repair were conducted and analyzed to derive codes, categories, and themes.
